To all whom it may concern.-

Be it known that I, RUDOLPH MORRELL, a citizen of the United States,residing at Winona, in the county of Winona and State of device, showingthe same applied to a part of a saw. Fig. 2 is an enlarged verticalsectional view, taken in the plane indicated by the dotted line w x onFig. 1, with the handles of the levers broken away. Fig. 3 is a planview of the device. Fig. 4 is a vertical section taken at right anglesto Fig. 2 and in the plane indicated by the dotted line y y thereon.Fig. 5 is an enlarged elevation, with parts in section and parts brokenaway, looking from the side opposite to that shown in Fig. 1. Fig. 6 isa perspective view of the swaging die removed. Fig. 7 is a perspectiveView of the stop for limiting the movements of the swaging lever, andFig. 8 is a perspective view of one of the adjusting screws for securingthe saw in the stock or head with the parts dissembled.

Referring by letter to said drawings, A, indicates the stock or headwhich may be formed of steel or other suitable material and is shown asof a circular form in outline, although it is obvious that theconfiguration may be changed according to the fancy or dictation of themechanic. This head is provided transversely at or near its center withan angular aperture a, to receive an anvil B, which is of a rectangularform in cross section, although it may be provided with more or lessfiat sides or faces, if found desirable. The head is also providedtransversely with a circular hole or aperture 1), which opens into theangular aperture a, asshown, and is designed to receive the swaging die0, as will be here- Serial No. 540,958. (No model.)

inafter more fully described. The head is slotted centrally andvertically from its under side for about one half of its altitude asshown at D, to receive the saw to be operated upon, and the machine isdesigned for oper- 5 ating upon either a straight or circular saw withequal ease and facility. Thehead is provided in each slotted branch E,with a transversely disposed screw tapped aperture d, to receive setscrews or bolts to engage a saw blade when placed in the slot D. r

F indicates a threaded bolt or screw which takes into the threadedaperture d, of one of the branches E, and is provided on its inner' endwith a milled or roughened head e, so as to impinge against one side ofthe saw blade and prevent any slipping thereon; a jam-nut f, beingemployed on this threaded and headed bolt for securing the same.

G indicates a set bolt or screw which is of a peculiar construction andtakes into the threaded aperture d, of the opposite branch E. This setscrew or bolt, as better shown in Fig. 8, of the drawings, is of apolygonal or angular form in cross section at its outer end g, 7:, toreceive a lever H, and is threaded externally for a portion of itslength to engage the threads in the aperture d. This screw is re cessedcentrally in its inner end for a sutticient distance as shown at h, andcrossing this aperture is a hole 71, to receive a pin 70.

I indicates a head which is milled orroughened at one end and itsopposite end is reduced as shown at Z, and is provided with an angularor circumferential groove m. The reduced portion of the head is designedto be placed in the recess or aperture h, and pin in, is designed toenter the groove m, so as to allow the head to swivel but yet prevent itfrom falling out.

By this construction it will be seen that the device can be quicklyapplied to and removed from the saw without disconnecting any of theparts, and the construction will permit of easy adjustment to saws ofvarious characters. 5 The fiat sided or angular anvil may be alsoreadily removed and replaced in the head so that when one side becomesimpaired or injured, it can be removed and turned so as to presentanother side to the swaging die.

J indicates the swaging lever. This lever is detachably secured to oneend of the swaging die 0, by means of a key n, which enters the grooveW, of said die, and a set screw or or bolt 19, may also be employed forholding the lever to the die as better shown in Fig. 2, of the drawings.This lever is provided at its lower end with a slot q, to receive a lugor arm a", which is designed to serve as a stop and limit the movementof said lever. This lug is secured to or formed on a plate or arm K,which has an eye 5, at one end and is received by a groove t, on thejam-nutf, although it obvious that this stop device might be secured tothe head by any suitable means.

In addition to serving as astop for limiting the swinging movement ofthe lever J, the lug r, of the arm K, serves to prevent lateral movementof the lever J, and endwise movement of the die 0, with respect to thehead A.

L indicates a gage. This gage is designed to adjust the device to sawsof different kinds and comprises a plate or casting havinga face a, tobear upon the teeth of the saw and a slotted branch 1;, rising from saidface. This gage is held to the head adjustably by means of an arm M,which is provided atits outer end with an eye to receive a bolt or screwN, which takes through the slot P, of the branch 1;, of the gage, and anut Q, may be employed for securing the slotted branch of the gage tosaid arm, as shown. The inner or opposite end of this arm is beveled orrounded on its under side as shown at R, and bears in a groove S, formedcentrally on the upper side of the head, A, and in which is a screwtapped aperture T. The arm is also slotted at its inner end and throughthis slot is passed a bolt U, which also takes into the screw tappedaperture T, of the head, and a bearing nut V, is placed on the boltbeneath the head thereof so as to straddle the slot in the arm and fixthe position of the same with respect to the head. By this constructionit will be seen that the arm is adjustably connected to the head, andthe gage is in turn adjustably con nected to the arm so that there willbe both an angular and a vertical adjustment afforded the gage upon thesaw.

In operation, after a saw has been adjustably secured as beforedescribed, and it is desired to swage the teeth all uniformly, it issimply necessary for the operator to grasp the lever J, so as to turnthe swaging die against the tooth and anvil backing the tooth, when thetooth will be quickly swaged and each and every tooth will be swagedalike. \Vhen the operator reverses the movement of the lever, he turnsthe swaging die so as to bring the longitudinal V-shaped groove W,thereof, in a position to admit the tooth between the die and anvil, andasboth walls of this groove are similar, when one becomes worn orinjured, it is simply necessary to remove the die, turn it, and thenreplace it, when the opposite Wall of the die can be used.

As will be readily observed the groove W, of the die 0, is much longerthan the width of a saw blade, and it will therefore, be appreciatedthat when a portion of one wall of said groove is worn, the die 0, maybe moved in the direction of its length and may be adjustably fixedthrough the medium of the lever J, and stop 4", on the arm K, so as topresent a new surface to a saw tooth. By reason of this, almost theentire length of both walls of the groove W, in die 0, must be wornbefore the die is rendered useless.

The anvil B of my improved swage is also adjustable in the direction ofthe width of the head A, so as to permit of a new or unused portion ofthe same being brought into operation. Said anvil'will therefore lastmuch longer.

Having described my invention, what I claim is- 1. In a saw swage, thecombination of ahead adapted .to receive a saw blade, an anvil arrangedtransversely in the head,the endwise adjustable rotary swagin g diearranged transversely in the head and having the longitudinal groove W,a hand lever arranged on the die, a key arranged in a recess of the handlever and the groove W, of the die,- a set screw taking through saidlever and engaging the die, and means for preventing lateral movement ofthe hand lever and consequently endwise movement of the die with respectto the head, substantially as specified.

2. In a saw swage, the combination of the head slotted in its under sideto receive a saw blade and grooved in its upper side, the slotted gageL, the arm M, adjustably connected with the gage L, by a bolt takingthrough the slot thereof and having the curved and slotted portionconforming to the curvature of the head and arranged in the groovethereof, and the headed bolt taking through the slot of the arm M, andinto the head, substantially as specified.
